Air scrubbers play a vital role in the wastewater treatment industry by effectively removing contaminants and odors from air streams. Systems like those below leverage advanced filtration techniques, such as biological processes or activated carbon, to address pollutants like hydrogen sulfide and volatile organic compounds, ensuring cleaner and safer air in treatment facilities.
DeLoach Industries Biological Tower Scrubber
The Biological Tower Scrubber from DeLoach Industries represents a cost-effective, innovative approach to air purification, particularly in municipal applications. It functions as a self-contained ecosystem, relying on bacteria initially seeded onto internal media substrate. These bacteria attach, breed and multiply, directly contacting contaminated air. They break down and digest contaminants, utilizing them as a food source for growth. In hydrogen sulfide treatment, the reaction produces sulphuric acid as a waste, lowering water pH and potentially harming the bacteria. To maintain a healthy environment, the scrubber requires the addition of a base like caustic. Gas-containing contaminants are forced into the tower, where they travel upward over a media bed cultured to support live microorganisms. Biological scrubbers require less maintenance and are easier to operate. Their adaptability may be challenged when faced with rapidly changing gas concentrations, and are best suited for concentrations that remain at a steady state. 941-371-4995; www.deloachindustries.com
Simple Solutions Distributing HRF Hi-Flow Radial Filter
The HRF Hi-Flow Radial Filter line from Simple Solutions Distributing are deep-bed radial molecular air scrubbers that capture VOCs in a broad range of environments. They feature an extremely low pressure drop, a small footprint, can handle airflows up to 2,800 CFM and are available in mild steel or stainless steel. They are suitable for air relief valves and lift stations. They can be used as a passive filter or as a complete system with a pressure blower and control panel. For indoor odor control a blower can be mounted on its inlet for a recirculating air purifier. The line holds between 1.5 and 7 cubic feet of activated carbon. They come complete with Norit Darco’s H2S activated carbon, specifically developed for removing hydrogen sulfide from air streams. Other media are available to match the application, including Microbe-sorb antiviral permanganate. 973-846-7817; www.industrialodorcontrol.com
